Neurotransmitter Receptor Influence on Behavior

Catha edulis (khat) is a plant grown in the countries around the Red Sea and on the eastern coast of Africa. Its leaves are chewed by the local people for their stimulant action. Its principal active constituents are cathinone and cathine, which have sympathomimetic actions. Migration of Africans from these countries has spread the habit of khat chewing to the West. Chewing khat has a number of important psychological and physical sequelae. ‘Khat-related’ psychosis is very similar to that seen following use of amphetamines.
